HWMonitor enables Nvidia RTX 50 series “GPU HotSpot” temperature support
HWMonitor has gained RTX 50 series GPU HotSpot monitoring support, and more apps will soon follow
CPUID’s HWMonitor 1.65 has been released and adds support for Nvidia GeForce RTX 50 series GPU HotSpot temperature monitoring. This is a first for a standard Windows PC application. Until now, this temperature was not accessible via publicly available applications, as Nvidia does not allow it to be monitored via its public API.
Unlike prior GeForce RTX series GPUs, Nvidia does not allow GPU HotSpot monitoring on its RTX 50 series GPUs. With the RTX 50 series, Nvidia only shows users a lower GPU temperature number. Until now, Nvidia’s GPU HotSpot thermals could only be measured using official Nvidia software, which is available to GPU repair technicians. For the RTX 50 series, GPU HotSpot temperatures are much higher than Nvidia’s reported GPU temperature.
HWMonitor has introduced HotSpot Temperature sensors for Nvidia RTX50 series GPUs!

HotSpot temperature support is coming to CapFrameX
CapFrameX v1.9.0 will support HotSpot temperature sensing for RTX 50-series GPUs. Now that HWMonitor supports Nvidia GPU HotSpot sensing, other PC monitoring application makers are working to enable this feature on their own apps. Soon, most GPU sensing applications should support GPU HotSpot temperature sensing, giving PC users more useful data.
CapFrameX version 1.9 will also be the first release to support the app’s new OSD. This new OSD is an in-house development that has less performance overhead than Rivatuner Statistics Server, which the app currently uses.

CPUID has not confirmed how it has enabled GPU HotSpot sensing support. It is likely that they have uncovered an undocumented method for recording this temperature. After all, if official Nvidia apps can sense it, other apps could too if they knew where to look. Since CapFrameX has confirmed upcoming support for GPU HotSpot sensing, it may be only a matter of time before other apps follow. Perhaps Nvidia will publicly document this path now that 3rd parties have uncovered it? After all, there may be no point in keeping it secret any longer.
